In this course, you will get a comprehensive overview of Python. You will start by laying the foundation and learning the introductory topics like operators, conditional statements, functions, loops, assignment statements, and more. You will then move onto more advanced topics such as classes and inheritance, iterators, list comprehensions, and dictionaries. Along with this, you will also get to explore the concept of testing and take a look at how GUI applications can be designed using Tkinter, Python's standard GUI library. 

By the time you're done, you'll be able to hit the ground running and be equipped with the tools that will allow you to be productive in Python.

Python 3: From Beginner to Advanced

# Data type conversion functions

To convert a value from one data type to another, it is often possible to use the name of the desired data type as if it were a function. For example:

| Conversion  | Result  |
|---|---|
| `int(5.7)` | 5  |
| `int("5")`  | 5  |
| `float(5)` | 5.0  |
| `float("5.7")`  | 5.7  |
| `bool("False")` | True  |
| `str([1,2,3])`  | '[1,2,3]' |

> **Note**: When working with Boolean data types, the following things are considered false: `False`, `None`, **0**, **0.0**, and the **empty string**.

Other data types that can be used as conversion functions are `list`, `set`, `tuple`, and `dict` (dictionary). A few important points to remember are:

- When you convert from a `dict` to any of the other types, you get **only the keys**, not the values.
- You can convert a `list`, `set`, or `tuple` to a `dict` **only if** the elements are **grouped in twos**, like, a list of 2- tuples (tuples with two elements).
- Sets have **no intrinsic ordering**, so converting to or from a set does not necessarily **preserve the order** of the elements.

# Difference between `type` and `isinstance` functions

The function `type(x)` will return a value that can be compared to the _name_ of a type (_not_ to a string representation of that name). For example, the test `type(5) == int` will return `True`, but `type(5) == "int"` will return `False`.

You will learn how to convert values from one data type to another in Python in this lesson.
